Growing lettuce

One of the things we love growing in our greenhouse is lettuce. It's wonderful to go and cut a head or some leaves and then come in and fix a salad.

We have some soft heads like butter crunch and Simpson and then some lettuce mixes.

We grow them in an easy hydroponic way by putting water and organic liquid fertilizer in a plastic containers that fit under the bed. We added some aeration that you get for aquariums (but you can use a whisk by hand).

You plant some seeds in some small cups that have holes in the bottom. Then you cut holes in some Styrofoam and put the cups in the holes. The roots grow out the bottom.
